Abstract
Dissociative chemisorption of O2 on the surface on Ni(110) has been investigated by the techniques of AES, LEED, and spin polarized inverse photoemission spectroscopy (SPIPES). SPIPES provides a unique method for studying the empty electronic states of the majority and minority spin bands separately and at the same time serves as a surface magnetometer. For increasing oxygen surface concentration [clean, O(2×1), O(3×1), saturated oxidation] it is found that the density of empty minority d states at EF decreases, whereas the features of the majority band are conserved up to the point of beginning bulk oxidation. This is taken as evidence for interactions of the adsorbate with the d levels of the substrate.
